This invention relates to new and useful improvements in edging stripsparticularly for flat roofing. I More particularly the invention relatesto a structure formed from a single sheet of metal which is capable ofexercising the function of a flashing, a parapet, a roof edge trim andwhen desired also serves as a ventilating louvre.

A primary object of this invention is to provide a roof edge for flatroofs which structure has protective as well as decorativecharacteristics.

A further object of the invention is to form a roof edge strip from asingle sheet of metal or equivalent resilient sheet material which stripprevents the entry of moisture to the interior of the building structureand provides a convenient drain for the passage of the condensedmoisture from the structure.

Another object of the invention is to provide from a single sheet ofmetal a roof edge strip for flat roofs which strip may embody a parapet,a flash and a drain-off portion.

An important object of the invention is to provide from a single sheetof metal a roof edge strip which may be sprung over a flat roofing toprovide the interior of the structure with ventilation while protectingthe building from the entry of undesired moisture.

These and other objectives of the invention will become apparent duringthe course of the following detailed description, taken with thedrawings wherein is shown a. preferred embodiment of the invention.

Figure 1 is a perspective view of a building structure embodying theroof edge of invention;

. Figure 2 is a view partially in section illustrating the attachment ofthe roof edge of invention to a building structure;

Figure 3 is a fragmentary front elevational view illustrating theformation of louvres integral with the roof edge strip of invention; and

Figure 4 is a view partially in section illustrating a modification ofthe strip of invention.

Referring to the drawings there is indicated generally at I in Figure 1a building structure having a flat roof 3 (Figure 2) and a roof edgestrip indicated generally at 5 is secured thereon. The roof edge strip 5comprises, as shown more clearly in Figure 2, a horizontally extendinganchor portion or flashing I secured to roof boards 9 beneath thematerial of the flat roof 3 and supported on joists II.

Extending upwardly from the anchor portion 1, forming an integralportion of the structure 5 and shown in the shape of an inverted U is aiii 3 Claims. (01. 1085-26) parapet portion I4 from which theredownwardly depends an outer skirt portion l5 substantially parallel withthe building wall. This portion I5 is adapted to close the open ends ofthe spaced joists II of the roof structure. The lower portion of theskirt I5 terminates in a trough portion I! having an aperture I9 in thebight thereof and extending from the inward side of portion I1 andparallel with the anchor portion I is a fascia 2i. The fascia 2| issecured to sheathing 23 and for thispurpose the fascia 2I is conveniently provided as at 25 with nail holes through which nails 21 may bedriven.

As shown in Figure 3 there is formed in the face of the dependent skirtportion I5 a ventilator indicated at 29 comprising louvre portions 3|,33 which define, respectively, with the skirt portion I5 longitudinalslots 35, 3! (Figure 2). The lower portions 3|, 33 are formed integralwith the skirt portion I5 as shown in Figure 3.

Figure 4 illustrates a modified form of the fascia of the structure ofinvention wherein the fascia is of relatively short length as shown atM. Fascia 4| is secured to the sheathing 23 through nail holes by nails41. With this arrangement, which is particularly useful when the anchorportion 1 is of great length in order to permit it to pass beyond thebuilding wall, the metal sheet roof edge strip 5 may be readily sprungover the joist II, roof boards 9 and sheathing 23 to form a completeedge trim for the building structure.

It will be understood that the roof edge strip 5 may be of any suitablydesired length and may comprise a number of short lengths joinedtogether with end to end relation in order to provide a continuouslength of edging for the building structure. The juncture of the stripsWhether in the central portion of the building or at the corners thereofmay be sealed if desired although the same is generally unnecessarysince the strip is adapted to drain to the aperture I9. It may be notedhowever that a rubber sealing strip between the junctures is effectiveto increase corrosion resistance.

It should also be noted that th provision of the slots 35, 3! rendersthe roof edge strip somewhat flexible and facilitates mounting of thesingle metal piece over the building structure.

When mounted in position on a flat roof as shown in Figure 1 theflashing l prevents the entry of moisture through the roof, while theparapet which may be of any desired height or contour, affordsprotection to the roof top from rain, snow, and so forth. The portion 2I prevents entry 3 of water and moisture from below, while rain and snowwhich may be driven throu h the slots 35, 31 will be readily collectedby the trough IT.

The stripping 5 also may be clearly adapted for roofs having a parapetin a building structure and in this case it is only necessary that thesheet metal be formed to enclose the parapet and have sufiicientresiliency to encompass the framework of the roof of the building. Anordinary sheet metal will normally be satisfactory for this purpose.

It will be understood that this invention is susceptible to modificationin order to adopt it to different usages and conditions and accordingly,it is desired to comprehend such modifications within this invention asmay fall within the scope of the appended claims.

I claim:

1. In combination, a fiat roof having the roof boards and sheathingthereof secured to opposed sides of spaced joists, an edge stricomprising an integral body of resilient sheet material having an anchorportion secured to said roof boards, a fascia secured to saidsheathing,- and a facing portion joining the outward ends of said anchorportion and fascia and spaced therefrom and extending above said roofportion to form a para pet and below said sheathing to form a trough,

and covering the edge of the roof, said facing portion having louvreoening's therein. I

2. The combination setfortli in claim 1, with 4 said trough portionhaving an aperture in the bight thereof.

3. In combination, a flat roof having the roof boards and sheathinthereof secured to opposed sides of spaced joists, an edge stripcomprising an integral body of resilient sheet material and comprisingan anchor portion secured to said roof boards, a fascia secured to saidsheathing, and the facing portion joinin the outward ends of saidanchorportion and said fascia and spaced therefrom to cover the edge ofsaid roof, said facing portion having a parapet extending above saidroof boards and a trough depending below said sheathing.
